Description of detection logic

IsRegressionChecked: Marked as regression because the three check build points were 0.05 greater than the baseline.
IsImprovementBase: Marked as not an improvement because the compare was not 5% less than the baseline, or the value was too small.
IsRegressionBase: Marked as regression because the compare was 5% greater than the baseline, and the value was not too small.
IsRegressionChecked: Marked as regression because the three check build points were 0.05 greater than the baseline.
IsRegressionWindowed: Marked as regression because 393.0513109756097 > 349.7612709697218.
IsChangePoint: Marked as a change because one of 4/16/2022 5:36:25 PM, 5/24/2022 3:42:52 PM, 5/31/2022 8:51:40 AM falls between 5/22/2022 6:37:49 PM and 5/31/2022 8:51:40 AM.
IsRegressionStdDev: Marked as regression because -72.8889833991559 (T) = (0 -388930.9138345244) / Math.Sqrt((7120457.191102944 / (28)) + (10746084.427696053 / (37))) is less than -1.9983405425199077 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (28) + (37) - 2, .025) and -0.1605226799241799 = (335134.26369223074 - 388930.9138345244) / 335134.26369223074 is less than -0.05.
IsImprovementBase: Marked as not an improvement because the compare was not 5% less than the baseline, or the value was too small.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
